Definitions

  • the present invention relates to a system and to a method apt to prevent the seeping of possible leakage in the ground surrounding an underground tank and, more specifically, to a system and to a method for the containment of possible leakage from an underground tank of gas or the like.
  • the existing norms provide that the same may be laid underground inside of a containment box made in reinforced concrete, mainly aimed in case of leakage at circumscribing the pollution to the sole ground contained inside of the box, thus preserving the surrounding ground.
  • Such containment boxes may be formed on site or prefab.
  • the use of this solution entails several practical and economical disadvantages.
  • a first disadvantage is entailed in the need to implement a box in reinforced concrete which may be formed on site or prefab.
  • a formbox structure for the forming of the concrete has to be provided, with the entailed complication due to the concrete casting.
  • the former has to be hauled from the manufacturing to the laying site, with the apparent problems related to the dimensions and weights thereof.
  • a second disadvantage is entailed in the fact that the concrete structure thus obtained should anyway be surface-treated with waterproofing paints so as to render the former suitable.
  • the object of the present invention is to overcome the abovementioned disadvantages of the state of the art providing a leakage containment system for an underground tank of simple and reliable implementation and providing an utmostly easy installation thereof, thus reducing the production and installation costs.
  • a leakage containment system for an underground tank comprising a containment structure apt to be located in a ground break, a tank support base internally located in said containment structure, and a tank apt to be fixedly arranged on said base, the system being characterised in that said containment structure is made in a flexible material.
  • the present invention further provides an assembling method of the leakage containment system characterised in that it comprises the following steps:
  • a ground break 1 apt to contain a tank 2 be made, wherein the latter is first positioned and then underground.
  • the system provides that the break be preferably made in a parallelepiped shape.
  • a sandy material layer 3 apt to level possible surface unevennesses of the bottom wall of the former is laid.
  • Said case 4 is of dimensions and shape apt to cover every wall of the break up to the outcropping of a portion of the case 4 at the perimetral edge area of the break 1.
  • case 4 may alternatively be implemented in any one material (natural or synthetic) provided the gas- and liquid-proofing, as well as the imputrescibility characteristics be maintained.
  • E.g., polyethylene, polypropylene, PVC and the like may be used.
  • the outcropping portion of case 4 be ground-secured with pegs 5 or with likewise securing means, removably located in the ground surrounding the break 1.
  • a second layer of sandy material 6 is laid, then a reinforced-concrete slab 7 apt to provide the support base for the tank 2 inside of the break 1 is arranged.
  • the layer 6 creates a laying bed and an interspace layer between the case 4 and the slab 7, thereby avoiding injuries to the case 4 due to a possible contact between the latter and the slab 7.
  • the tank 2 is positioned onto the slab 7 in the known manner.
  • the break 1 with the tank 2 positioned therein may be filled up as usual, i.e., with riddled earth, up to a set height so as to underground the anodes, and then filling up the remaining space with sand, like, e.g., inert river or pit sand or the like until covering up the whole system, including the portion of the case 4 outcropping from the break 1 and secured by the pegs 5.
  • sand like, e.g., inert river or pit sand or the like until covering up the whole system, including the portion of the case 4 outcropping from the break 1 and secured by the pegs 5.
  • the system of the present invention is also apt to provide the cathodic protection of the tank 2 in compliance to the existing norms. More precisely, it may be provided that in the underground of the break one or more sacrificial anode 8 and related reference anode 9 be positioned, as it is already known in the state of the art. Furthermore, the system of the present invention is suitable to the assembling of a control well 10 of the tank 2 containing the controlling and monitoring means thereof and usually provided at the top portion of the tank 2 outcropping from the break 1, as it is already known in the state of the art.
  • the system of the present invention has a first advantage in that it provides a leakage containment system for an underground tank having an utmostly simple, and concomitantly extremely effective, installation.
  • a second advantage of the system of the present invention is provided by the fact that, due to the utmost easiness of implementation and hauling exhibited by the case 4 it overcomes all the problems related to the containment boxes in concrete or polyethylene shell-vaults, and to the containment systems of the state of the art.
  • a third advantage of the system of the present invention is provided by the extremely low cost of the case 4 with respect to the containment systems of the state of the art.
